Is There A Native LINQ Way To Return A Typed Collection
Apr 18, 2011Is this the most straight forward way to return a typed collection?Here's the key line of code which returns a implicit type of IEnumerable that used to manually loop through to manually recreated a TYPED collection. Is there any native LINQ way to return a typed sorted collection without this recreating of the collection? [code]

Jan 17, 2012I am using a Strongly Typed Dataset as DAL. I want to return a single column from my table for that i wrote the code as

VS 2008 - LINQ Query Against A Typed Datatable That Will Return Me Duplicated Data?
Jan 25, 2010I'm trying to do a LINQ Query against a typed datatable that will return me duplicated data.With out going into too much detail, here's the basic setup:
strCode1 - string type
intCode1 - int32 type
intAdjustor - int32
There are more fields but these are the ones that are important.I'm going to do my best to describe this, as it's kind of confusing.In theory intCode1 is a key for strCode1 (hence the names). So each time intCode1 is duplicated, the same strCode1 should appear. Example:
[code]...
Ultimately I'd like to get a List(Of T) - where T is my typed data row. In SQL, I would simply use a sub query, to get a distinct list of strCode1 and intCode1, then do a count, grouped by strCode1 where I get more than one row.I'm not sure how to translate that into LINQ, AND get the original types data rows returned in a list.
Return An Object As The Return Value Through A RealProxy Transparent Proxy?
Oct 7, 2010I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

Asp.net - Provide Strongly Typed Access To The Session Object
Nov 6, 2009What is the best way to provide strongly typed access to the session object? I am planning on turning on Option Strict, which is causing the compiler to complain about my lazy programming technique of directly accessing the session object:
Dim blah As Integer = Session("Blah")
My initial thought is to create a class that wraps the session and provides strongly typed properties for the information stored in the session. However, I cannot decide if the class should be a singleton, or instantiated on every use, or where the code should reside (i.e. within the web project or within a class library).
I'm leaning towards a singleton in my class library, but I don't know if that is the best solution, or if I am missing any other possibilities.
Proposed Solution:
Public Class SessionAccess
Public Shared Property Blah(ByVal session As HttpSessionState) As Integer

View 2 RepliesNPV In Excel And VB Return Different Values?
Nov 30, 2010If a use the NPV() function in Excel (2010) with a discount rate of 5% and 10 cells that each contain 505,000 the resulting NPV function call "=NPV(5%,C2:C11)" returns the value of 3,899,496.
If I use the Financial.NPV() method in the Microsoft.VisualBasic namespace (in my C# application) and pass in a discount rate of 5% (as a double) and an array of 10 doubles with a value of 505,000 each, the VB function returns the much lower value of 100,999.99 (plus a few more decimals).

Feb 18, 2012What I need to do is to have my program look at 2 different values then return a value.
Here's an example:
If my tube material = SA-214 and the tube gauge = 20 then my tube wall thickness = .032. The thing is I have 5 different types of tube material and 12 different tube gauges so based on which tube material is selected and which tube gauge is selected the tube wall thickness will vary. So if I select a TM of SA214 and a TG of 14 then my tube wall will be .076.
